Coleman Kane 7c0618bdb7 Linux 6.5 compat: blkdev changes
Multiple changes to the blkdev API were introduced in Linux 6.5. This
includes passing (void* holder) to blkdev_put, adding a new
blk_holder_ops* arg to blkdev_get_by_path, adding a new blk_mode_t type
that replaces uses of fmode_t, and removing an argument from the release
handler on block_device_operations that we weren't using. The open
function definition has also changed to take gendisk* and blk_mode_t, so
update it accordingly, too.

Implement local wrappers for blkdev_get_by_path() and
vdev_blkdev_put() so that the in-line calls are cleaner, and place the
conditionally-compiled implementation details inside of both of these
local wrappers. Both calls are exclusively used within vdev_disk.c, at
this time.

Add blk_mode_is_open_write() to test FMODE_WRITE / BLK_OPEN_WRITE
The wrapper function is now used for testing using the appropriate
method for the kernel, whether the open mode is writable or not.

Emphasize fmode_t arg in zvol_release is not used

Coleman Kane 3ff9e4f8ac Linux 6.5 compat: use disk_check_media_change when it exists
When disk_check_media_change() exists, then define
zfs_check_media_change() to simply call disk_check_media_change() on
the bd_disk member of its argument. Since disk_check_media_change()
is newer than when revalidate_disk was present in bops, we should
be able to safely do this via a macro, instead of recreating a new
implementation of the inline function that forces revalidation.

Coleman Kane 211868b5d0 Linux 6.5 compat: register_sysctl_table removed
Additionally, the .child element of ctl_table has been removed in 6.5.
This change adds a new test for the pre-6.5 register_sysctl_table()
function, and uses the old code in that case. If it isn't found, then
the parentage entries in the tables are removed, and the register_sysctl
call is provided the paths of "kernel/spl", "kernel/spl/kmem", and
"kernel/spl/kstat" directly, to populate each subdirectory over three
calls, as is the new API.

Brian Behlendorf 837e426c1f Linux: Never sleep in kmem_cache_alloc(..., KM_NOSLEEP) (#14926)
When a kmem cache is exhausted and needs to be expanded a new
slab is allocated.  KM_SLEEP callers can block and wait for the
allocation, but KM_NOSLEEP callers were incorrectly allowed to
block as well.

Resolve this by attempting an emergency allocation as a best
effort.  This may fail but that's fine since any KM_NOSLEEP
consumer is required to handle an allocation failure.

Rich Ercolani 692f78045e Workaround issue cleaning up automounted snapshots on Linux
On Linux, sometimes, when ZFS goes to unmount an automounted snap,
it fails a VERIFY check on debug builds, because taskq_cancel_id
returned ENOENT after not finding the taskq it was trying to cancel.

This presumably happens when it already died for some reason; in this
case, we don't really mind it already being dead, since we're just
going to dispatch a new task to unmount it right after.

So we just ignore it if we get back ENOENT trying to cancel here,
retry a couple times if we get back the only other possible condition
(EBUSY), and log to dbgmsg if we got anything but ENOENT or success.

(We also add some locking around taskqid, to avoid one or two cases
of two instances of trying to cancel something at once.)

Unlike regular receive, raw receive require destination to have the
same block structure as the source.  In case of dnode reclaim this
triggers two special cases, requiring special handling:
 - If dn_nlevels == 1, we can change the ibs, but dnode_set_blksz()
should not dirty the data buffer if block size does not change, or
durign receive dbuf_dirty_lightweight() will trigger assertion.
 - If dn_nlevels > 1, we just can't change the ibs, dnode_set_blksz()
would fail and receive_object would trigger assertion, so we should
destroy and recreate the dnode from scratch.

George Amanakis c12b5829e1 Fix the L2ARC write size calculating logic (2)
While commit bcd5321 adjusts the write size based on the size of the log
block, this happens after comparing the unadjusted write size to the
evicted (target) size.

In this case l2ad_hand will exceed l2ad_evict and violate an assertion
at the end of l2arc_write_buffers().

Fix this by adding the max log block size to the allocated size of the
buffer to be committed before comparing the result to the target
size.

Also reset the l2arc_trim_ahead ZFS module variable when the adjusted
write size exceeds the size of the L2ARC device.

Jeremy Visser c5bbd80cb9 zfs-dkms rpm: simplify scriptlets, fix uninstall
Two problems led to unexpected behaviour of the scriptlets:

1) Newer DKMS versions change the formatting of "dkms status":

   (old) zfs, 2.1.2, 5.14.10-300.fc35.x86_64, x86_64: installed
   (new) zfs/2.1.2, 5.14.10-300.fc35.x86_64, x86_64: installed

   Which broke a conditional determining whether to uninstall.

2) zfs_config.h not packaged properly, but was attempted to be read
   in the %preun scriptlet:

   CONFIG_H="/var/lib/dkms/zfs/2.1.2/*/*/zfs_config.h"

   Which broke the uninstallation of the module, which left behind a
   dangling symlink, which broke DKMS entirely with this error:

     Error! Could not locate dkms.conf file.
     File: /var/lib/dkms/zfs/2.1.1/source/dkms.conf does not exist.

This change attempts to simplify life by:

*  Avoiding parsing anything (less prone to future breakage)
*  Uses %posttrans instead of %post for module installation, because
   %post happens before %preun, while %posttrans happens afterwards
*  Unconditionally reinstall module on upgrade, which is less
   efficient but the trade-off is that it's more reliable

Alternative approaches could involve fixing the existing parsing bugs
or improving the logic, but this comes at the cost of complexity and
possible future bugs.

Low-power 35d43ba8ea Workaround for Linux PowerPC GPL-only cpu_has_feature()
Linux since 4.7 makes interface 'cpu_has_feature' to use jump labels on
powerpc if CONFIG_JUMP_LABEL_FEATURE_CHECKS is enabled, in this case
however the inline function references GPL-only symbol
'cpu_feature_keys'.

ZFS currently uses 'cpu_has_feature' either directly or indirectly from
several places; while it is unknown how this issue didn't break ZFS on
64-bit little-endian powerpc, it is known to break ZFS with many Linux
versions on both 32-bit and 64-bit big-endian powerpc.

Until this issue is fixed in Linux, we have to workaround it by
overriding affected inline functions without depending on
'cpu_feature_keys'.

Shaan Nobee 9e5a297de6 Speed up WB_SYNC_NONE when a WB_SYNC_ALL occurs simultaneously
Page writebacks with WB_SYNC_NONE can take several seconds to complete
since they wait for the transaction group to close before being
committed. This is usually not a problem since the caller does not
need to wait. However, if we're simultaneously doing a writeback
with WB_SYNC_ALL (e.g via msync), the latter can block for several
seconds (up to zfs_txg_timeout) due to the active WB_SYNC_NONE
writeback since it needs to wait for the transaction to complete
and the PG_writeback bit to be cleared.

This commit deals with 2 cases:

- No page writeback is active. A WB_SYNC_ALL page writeback starts
  and even completes. But when it's about to check if the PG_writeback
  bit has been cleared, another writeback with WB_SYNC_NONE starts.
  The sync page writeback ends up waiting for the non-sync page
  writeback to complete.

- A page writeback with WB_SYNC_NONE is already active when a
  WB_SYNC_ALL writeback starts. The WB_SYNC_ALL writeback ends up
  waiting for the WB_SYNC_NONE writeback.

The fix works by carefully keeping track of active sync/non-sync
writebacks and committing when beneficial.

Alexander Motin c1b9dc735f Mark TX_COMMIT transaction with TXG_NOTHROTTLE.
TX_COMMIT has no on-disk representation and does not produce any more
dirty data.  It should not wait for anything, and even just skipping
the checks if not waiting gives improvement noticeable in profiler.

Alexander Motin e271cd7a65 Fix positive ABD size assertion in abd_verify().
Gang ABDs without childred are legal, and they do have zero size.
For other ABD types zero size doesn't have much sense and likely
not working correctly now.

Mariusz Zaborski 7d26967d4e Move zap_attribute_t to the heap in dsl_deadlist_merge
In the case of a regular compilation, the compiler
raises a warning for a dsl_deadlist_merge function, that
the stack size is to large. In debug build this can
generate an error.

Move large structures to heap.

Luís Henriques 671b1af1bc Fix NULL pointer dereference when doing concurrent 'send' operations
A NULL pointer will occur when doing a 'zfs send -S' on a dataset that
is still being received.  The problem is that the new 'send' will
rightfully fail to own the datasets (i.e. dsl_dataset_own_force() will
fail), but then dmu_send() will still do the dsl_dataset_disown().

rob-wing f786232b2a FreeBSD: don't verify recycled vnode for zfs control directory

    #15 0xffffffff808ae50c at amd64_syscall+0x10c
    #16 0xffffffff808876bb at fast_syscall_common+0xf8

The page fault occurs because vgonel() will call VOP_CLOSE() for active
vnodes. For this reason, define vop_close for zfsctl_ops_snapshot. While
here, define vop_open for consistency.

After adding the necessary vop, the bug progresses to the following
panic:

    panic: VERIFY3(vrecycle(vp) == 1) failed (0 == 1)
    cpuid = 17
    KDB: stack backtrace:
    #0 0xffffffff805e29c5 at kdb_backtrace+0x65

    #8 0xffffffff81a39069 at sfs_vgetx+0x149
    #9 0xffffffff81a39c54 at zfsctl_snapdir_lookup+0x1e4
    #10 0xffffffff80661c2c at lookup+0x45c

    #14 0xffffffff808b5ecc at amd64_syscall+0x10c
    #15 0xffffffff8088f07b at fast_syscall_common+0xf8

This is caused by a race condition that can occur when allocating a new
vnode and adding that vnode to the vfs hash. If the newly created vnode
loses the race when being inserted into the vfs hash, it will not be
recycled as its usecount is greater than zero, hitting the above
assertion.

Fix this by dropping the assertion.
